4 of 5 IMPRESSIVE December 3, 2023
Reviewer: David Allen Rivera from Millersburg, PA United States  
I had another brand, that I never even used that much, but the display went bad. I had an older non-digital display Nitecore model, which lasted a long-time, but the insulation came off the wiring at the joint, and I believe the wiring began separating and I wasn't getting uniform charging. But I got my money's worth, and felt confident enough in the brand name to try another one. I've used it once, it works well. It is sturdy and well-made, and I'm optimistic on it's long-term operation.

5 of 5 Battery charger October 9, 2023
Reviewer: Scott C  
I have about 8 nitcore flashlights and they are great.  I just update 2 new one with the larger 500 battery, so also needed to buy a new charger that the larger batteries fit in.

5 of 5 Excellent product September 27, 2023
Reviewer: Gordon Estabrook from Denville, NJ United States  
I use my batteries all the time and need to have them available quickly.  This charger gives me the option to charge and carry multiple batteries during my work day. It also tells you the power levels on the batteries.  I like that feature
